About 50 are believed to have been built; the only known "survivor" is in the exposition of the RRR scooter museum in Eggenburg, Austria.

Libelle is a German cipher system, developed by the Federal Office for Information Security. The algorithm is not published, in an attempt to make cryptanalysis more difficult (following the principle of security through obscurity and against Kerckhoffs's principle). In order to keep the algorithm secret, it is only distributed as a microchip named Pluto and not as a piece of software.
It is possible to have a secret cipher algorithm while still reaping the benefits of public cryptography research: one way is to make a non-weakening change to a public algorithm, like changing the Nothing up my sleeve numbers, or chaining the public cipher with an unrelated secret cipher.
A BSI specification document about Pluto gives these numbers: 64 bit block size, 160 bit key size. Supported modes: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB)/ Output Feedback (OFB) with 1,8,16,32 or 64 bits.
A libelle is a political pamphlet or book which slanders a public figure. Libelles held particular significance in France under the Ancien Régime, especially during the eighteenth century, when the pamphlets’ attacks on the monarchy became both more numerous and venomous. In recent years, cultural historian Robert Darnton has written on the libelles, arguing for the subversive power that the libelles of the late eighteenth century exercised in undermining monarchical authority.
Libelle is the name of a German air-borne toy made by SCHENY in late 1950s or early 1960s.
